Good Day Sir/Madam.
Trust you well
Our team has taken over a DNN site that we have limited knowledge on. We currently running DNN7 and trying to migrate existing apps to DNN8 on a new server.
We successfully compiled and install an app as an module/extenstion on DNN8, but when opening the homepage of the app, there is critical exception thrown. We have other apps running on the same site with no issues, this proves the DNN local database(SQL Express) is accessible. The only difference is that the app in question is deployed as an extension
Please can you advise the possible causes for this exception or what could we look at.
InnerMessage:Exception has been thrown by the target of an invocation.

Any advice will be valuable. Thank you very much!
That is a very ambiguous message. The root cause could be anything at this point. You should try pulling a copy of this website into a development environment, and then duplicating the error(s) while debugging the site.
In addition, you may be able to get lucky and find more related errors in the Log4NET log file.
